CVE-2022-41627 — Alivecor Kardiamobile Firmware security vulnerability

High CVSS 7.6

The physical IoT device of the AliveCor's KardiaMobile, a smartphone-based personal electrocardiogram (EKG) has no encryption for its data-over-sound protocols. Exploiting this vulnerability could allow an attacker to read patient EKG results or create a denial-of-service condition by emitting sounds at similar frequencies as the device, disrupting the smartphone microphone’s ability to accurately read the data. To carry out this attack, the attacker must be close (less than 5 feet) to pick up and emit sound waves.

Matched remediation archetype

Cryptography, certificate, signature, and channel validation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Inventory affected algorithms, key uses, trust stores, certificate validation settings, random sources, and plaintext channels across clients and services.
  • Determine which secrets, identities, signatures, or data protections depend on the affected primitive or validation path.
  • Check debug, compatibility, fallback, and hostname or audience override settings in build and runtime configuration.

Remediate safely

  • Use a maintained platform cryptographic API with approved algorithms, modes, parameters, randomness, and full peer identity validation.
  • Remove insecure fallback and validation bypasses; separate keys by purpose and load them from managed secret storage.
  • Plan rotation or reissuance for affected keys, certificates, tokens, hashes, or ciphertext and document compatibility sequencing.
